 I acquired master and doctoral degrees at Prof. Maeshima lab, and I am now engaged in research as assistant professor. I have studied the H+- PPase for several years, and now focused on PPi metabolism in collaboration with Dr. Ali Ferjani. In this study, I revealed the importance of the cooperative contribution of soluble PPases and H+-PPase in PPi homeostasis. I want to further shed light on PPi world, which has been somewhat hidden in the shadow of ATP. Also, I previously reported that the structure of plant vacuoles is affected in transgenic plants by the dimerization of GFP attached to H+-PPase (Segami et al., 2014, Plant Cell). Even now regular GFP, which has a dimeric site, is still in use worldwide. Contributing to the eradication of this issue is another personal goal.
